Custom AI Software Development FAQs
Answers for founders and product leaders.
What is custom AI software development?
Custom AI software development is building software products with AI at their core — designed specifically for your business, not off-the-shelf. It includes everything from AI SaaS platforms and mobile apps to internal tools powered by machine learning, LLMs, or computer vision.
How much does an AI MVP cost?
Most MVPs range from $25K-$75K depending on complexity. Simple AI integrations cost less; custom models and complex platforms cost more. Our free scoping call gives you an honest estimate — no surprises later.
How long until we can launch?
Typical MVPs launch in 8-12 weeks. We work in weekly sprints with demos, so you see progress constantly and can adjust priorities. Complex platforms take 4-6 months.
Do you provide ongoing support after launch?
Yes. Every product includes a warranty period, and most clients continue with a maintenance plan. We handle hosting, monitoring, updates, and new features — so you can focus on customers.
